Iron Ore Hematite Magnetizing Roasting

  • iron ore explained

    the two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. magnetizing roasting uses temperatures between 700 and 900 °c for a time of under 1 hour to produce an iron concentrate (fe 3 o 4) to be used for iron smelting.
